Changes in Arctic vegetation can have important implications for trophic interactions and ecosystem functioning leading to climate feedbacks. Plot-based vegetation surveys provide detailed insight into vegetation changes at sites around the Arctic and improve our ability to predict the impacts of environmental change on tundra ecosystems. Here, we review studies of changes in plant community composition and phenology from both long-term monitoring and warming experiments in Arctic environments. We find that Arctic plant communities and species are generally sensitive to warming, but trends over a period of time are heterogeneous and complex and do not always mirror expectations based on responses to experimental manipulations. Our findings highlight the need for more geographically widespread, integrated, and comprehensive monitoring efforts that can better resolve the interacting effects of warming and other local and regional ecological factors.

The Circumpolar Biodiversity Monitoring Programme (CBMP) provides an opportunity to improve our knowledge of Arctic arthropod diversity, but initial baseline studies are required to summarise the stat...
Many studies of individual sites have revealed biotic changes consistent with climate warming (e.g., upward elevational distribution shifts), but our understanding of the tremendous variation among st...
Global warming is significantly altering arctic marine ecosystems. Specifically, the precipitous loss of sea ice is creating a dichotomy between ice-dependent polar bears and pinnipeds that are losing...
Climate change has irrevocable consequences for the otherwise well-preserved archaeological deposits in the Arctic. Vegetation changes are expected to impact archaeological sites, but currently the ef...
Peatlands are known as NO sinks or low NO sources due to nitrogen (N) limitation. However, climate warming and N deposition can modulate this limitation, and little is known about the combinative effe...
Two patient warming systems will be compared with 40 patients each in a convective warming group (BairHugger, Arizant) and in a conductive warming group (HotDog, Augustine Biomedical). ...
Intraoperative active warming is usually performed by skin warming. There are several forced-air systems on the market; forced air warming is generally described as the most effective yet ...
The aim of this study is to assess the effectiveness of EnsoETM as a supplemental warming device compared to the standard of care warming practice in patients having major surgery.
The purpose of this study is to determine if local warming of surgical wounds improves healing and helps prevent infection. The investigators want to see if warming surgical incisions impr...
Trauma is the leading cause of death in young adults, bleeding and infection are major concomitant problems. We test the hypothesis that fast, perioperative warming with an endovascular ca...
The Arctic Ocean and the lands in it and adjacent to it. It includes Point Barrow, Alaska, most of the Franklin District in Canada, two thirds of Greenland, Svalbard, Franz Josef Land, Lapland, Novaya Zemlya, and Northern Siberia. (Webster's New Geographical Dictionary, 1988, p66)
Experimental animal models for human AUTOIMMUNE DISEASES OF THE NERVOUS SYSTEM. They include GUILLAIN-BARRE SYNDROME (see NEURITIS, AUTOIMMUNE, EXPERIMENTAL); MYASTHENIA GRAVIS (see MYASTHENIA GRAVIS, AUTOIMMUNE, EXPERIMENTAL); and MULTIPLE SCLEROSIS (see ENCEPHALOMYELITIS, AUTOIMMUNE, EXPERIMENTAL).
A preconceived judgment made without adequate evidence and not easily alterable by presentation of contrary evidence.
Groups that serve as a standard for comparison in experimental studies. They are similar in relevant characteristics to the experimental group but do not receive the experimental intervention.
A prolonged seizure or seizures repeated frequently enough to prevent recovery between episodes occurring over a period of 20-30 minutes. The most common subtype is generalized tonic-clonic status epilepticus, a potentially fatal condition associated with neuronal injury and respiratory and metabolic dysfunction. Nonconvulsive forms include petit mal status and complex partial status, which may manifest as behavioral disturbances. Simple partial status epilepticus consists of persistent motor, sensory, or autonomic seizures that do not impair cognition (see also EPILEPSIA PARTIALIS CONTINUA). Subclinical status epilepticus generally refers to seizures occurring in an unresponsive or comatose individual in the absence of overt signs of seizure activity.
